1. Turn off the system, including any attached peripherals, and disconnect the power
cable from the electrical outlet.
2. Open the system cover.
See your system Installation and Troubleshooting Guide for specific instructions,
if needed.
3. Remove the air blower, if present (see Figure 1-4).
a. Unplug the Y-shaped air blower power cable from the interposer board.
b. Position your right thumb on the outside of the power supply enclosure
beside the narrower front part of the air blower.
c. Push firmly on the power supply enclosure to move it slightly away from the
air blower and allow extra clearance to remove the air blower.
d. With your left hand, pull the front of the air blower upward and away from
the power supplies to unseat it. You should hear it unsnap.
By pulling the air blower slightly away from the power supplies, you avoid the
need to use excessive force to clear the power supply enclosure.
e. Slide the air blower slightly up and toward the front of the chassis until the
metal tab at the back right of the air blower slides out of the small slot at the
top back of the chassis.
